2. The composition as described in claim 1, wherein each of w, x, y, and z has a numerical value between about 1 and about 50.

3. The composition as described in claim 1, wherein the sum of x+y, x+y+z or w+x+y+z, or combinations thereof, has an average value ranging from about 6 to about 20.

4. The composition as described in claim 1, wherein R comprises alkyl groups having carbon chain lengths ranging from C.sub.4 to C.sub.10.

5. The composition as described in claim 4, wherein R comprises alkyl groups ranging from C.sub.6 to C.sub.8.

6. The composition as described in claim 2, wherein the composition has the formula:

7. The composition as described in claim 2, wherein the polyhydric alcohol is selected from the group consisting of glycerol, polyethylene glycol, propylene glycol, ribitol, and sorbitol.

8. The composition as described in claim 2, wherein the polyhydric alcohol is selected from the group consisting of glycerol and polyethylene glycol.

9. The composition as described in claim 2, wherein the composition is added to a formulation, the formulation being chosen from the group consisting of a cosmetic, a household product, a personal care product, a pharmaceutical product and a veterinary product.

10. The composition as described in claim 9, wherein the personal care product is chosen from the group consisting of a sanitizer, a hand lotion, an antibacterial hand lotion, a shampoo, an anhydrous gel, a sunscreen, a hair gel, a moisturizing product, a moisturizing cream, a moisturizing mist, a moisturizing mist and mousse, a moisturizing lotion, a cold process lotion and a self foaming cleanser.

11. The composition as described in claim 9, wherein the formulation is applied to the skin or hair of a mammal.

12. The composition as described in claim 11, wherein the mammal is a human.

13. The composition as described in claim 9, wherein the composition comprises from about 0.001% to about 100% by weight of the formulation.

14. The composition as described in claim 9, wherein the composition comprises from about 0.01% to about 10% by weight of the formulation.

15. The composition as described in claim 9, wherein the composition comprises from about 0.15% to about 3% by weight of the formulation.

16. The composition as described in claim 2, wherein the composition is further characterized by having an HLB value ranging from greater than 10 to about 20.

17. The composition as described in claim 9, further comprising at least one agent selected from the group consisting of emollients, film-formers, viscosity modifiers, colorants, anti-irritants, preservatives, buffering agents, humectants and mixtures thereof.

18. The composition as described in claim 2, wherein the composition has antimicrobial activity against Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa.

19. An antimicrobial composition consisting essentially of a substituted polyhydric alcohol and an ester of a fatty acid, the composition having the structure of:wherein R' is H, CH.sub.3, CH.sub.2-- (O[CH.sub.2].sub.n).sub.z--OH, orand wherein x+y, x+y+z or w+x+y+z, or combinations thereof, has an average value ranging from about 6 to about 100; wherein R is a hydrocarbon comprising from about 3 to about 19 carbons; wherein n is an integer ranging from about 2 to about 4 or combinations thereof; and wherein m is an integer ranging from 0 to about 6; the composition being present in a quantity sufficient to effectively inhibit the infectious activity of a pathogenic microorganism; and a physiologically acceptable diluent.

20. A process for inhibiting infection by a pathogenic microorganism in a subject in need thereof comprising administering to the subject an amount of a composition consisting essentially of a substituted polyhydric alcohol and an ester of a fatty acid, the composition having the structure of:wherein R' is H, CH.sub.3, CH.sub.2-- (O[CH.sub.2].sub.n).sub.z--OH, orand wherein x+y, x+y+z or w+x+y+z, or combinations thereof, has an average value ranging from about 6 to about 100; wherein R is a hydrocarbon comprising from about 3 to about 19 carbons; wherein n is an integer ranging from about 2 to about 4 or combinations thereof; and wherein m is an integer ranging from 0 to about 6; the composition being administered in a concentration effective to inhibit the infectious activity of the microorganism.

21. The process as described in claim 20, further comprising the step of adding the composition to a formulation, the formulation being chosen from the group consisting of a cosmetic, a household product, a personal care product, a pharmaceutical product and a veterinary product.

22. The process as described in claim 21, wherein the personal care product is chosen from the group consisting of a sanitizer, a hand lotion, a shampoo, an anhydrous gel, a sunscreen, a hair gel, a moisturizing cream, a moisturizing mist, a moisturizing mist and mousse, a moisturizing lotion, a cold process lotion and a self foaming cleanser.

23. The process described in claim 21, comprising the step of applying the composition to the skin or hair of a mammal.

24. The process as described in claim 23, wherein the mammal is a human.

25. The process as described in claim 22, wherein the composition has antimicrobial activity against Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa.

26. The process as described in claim 22, wherein the composition has antimicrobial activity against Candida albicans, Aspergillis niger and Penicillium notatum.

27. An antimicrobial composition consisting essentially of a glycerol ester of an ethoxylated fatty acid as described in claim 2; and water.

28. The antimicrobial composition as described in claim 27, wherein the fatty acid comprises ethylhexanoate.

29. An antimicrobial composition consisting essentially of a composition having the formula:wherein x+y+z has an average value of 18.
